Hi,
I am using Compaq Array Configuration Utility with RAID 1+0. I have booted the system from Slot1.
I would like to know, if I insert a new disk into Slot0, would the data be backed up automatically from slot1 to slot0.
I want the source of data to be slot1 and destination as slot0. I dont want the reverse to happen. Can you pls confirm if I can obtain the desired results.
Thx...

Re: RAID 1+0 Configuration
Vijay,
The data won't be "backed up" to the new hdd in Slot 0. The controller will have marked ID 0 as failed, then when you put the replacement hard drive in the slot, it will rebuild the online hdd to the failed hdd. In a raid 1+0, it will copy the data over, in a RAID 5, it would rebuild the drive by recalculating parity. The controller wouldn't do the reverse scenario that you mentioned because it is in a failed state.
Ciao,
Greg

Hi Vijay,
Be assured that data will be transfered or copied to the replacement (HP terminology used in the Array Rebuilding/Restoring Techniques document - TARGET DRIVE) drive as slot 0 has already been marked by the controller as failed. So no matter whatever drive you insert in slot 0 will get overwritten by data from the drive in slot 1.
Let me know if you require further information.
Hope this is of help and don't forget to assign points:)
